Hi Lonnie, The P45’s rotating barrel makes shooting the powerful .45 ACP round as tame as the 9mm. Also featured is an innovative polyamide handle that's stronger and gives you enhanced reliability and easier field stripping. And the stylish curved slide provides excellent handling and ergonomics with less lift and recoil.Grand Power P45 GPP45
